Accupro 315599 Square End Mill 5/8 in 3 Flute Carbide Zrn

Product Description

The ACCUPRO 315599 is a solid carbide square end mill designed for precision milling operations in metalworking and machining applications. It features a 5/8-inch mill diameter, a 3/4-inch length of cut, and a 3-flute spiral design with a 37-degree helix angle. The ZrN (zirconium nitride) coating improves wear resistance and reduces built-up edge during high-speed cutting. Micrograin carbide construction provides hardness and edge retention. The centercutting geometry allows plunge milling in addition to peripheral and slot milling. This end mill is installed by machinists and CNC operators working with tight tolerances on mill machines and machining centers.

This end mill is suited for slotting, profiling, and contouring in ferrous and non-ferrous materials where a durable, coated carbide tool is required. The extended reach configuration, with a 1-5/8-inch reach length and 3-1/2-inch overall length, accommodates deeper pockets and workpiece features that shorter tools cannot access. Right-hand cut and right-hand flute orientation match standard spindle rotation on most vertical and horizontal machining centers. It is sold individually and is appropriate for both production and job-shop environments.

Key Features

• Solid micrograin carbide construction for edge retention and dimensional stability
• ZrN coating reduces friction and extends tool life in demanding cuts
• 37-degree helix angle promotes efficient chip evacuation
• Centercutting design enables plunge entry without a pre-drilled hole
• Extended reach with 1-5/8-inch reach length for deep-pocket access
• Right-hand cut and right-hand flute for standard CNC spindle compatibility

Compatibility

Designed as an OEM-style replacement or direct-use solid carbide square end mill for standard 5/8-inch collet or end mill holder systems on vertical and horizontal machining centers.

Installation Notes

Installation is performed by machinists using an appropriate collet chuck or end mill holder rated for the 5/8-inch shank diameter. Ensure the spindle is fully stopped and the machine is in a safe, locked-out state before tool changes. Verify shank seating depth and runout with a dial indicator before beginning cuts. Follow machine manufacturer torque specifications for the tool holder being used.
